It is necessary to bear in mind another point. Science has started to use the term “expanding universe” very recently, but the thing – the element – which is called the brahman by the Upanishads, means the expanding. That is the meaning of the word brahman. The meaning of brahman is not God, but the element that is constantly expanding. The words brahman and vistala – expanse – are derived from the same root. They are derivations of the same word. So, the meaning of brahman is that which goes on and on expanding. It is not that it has expanded or spread; it is not a static condition, but it is that which is constantly expanding. The activity is going on. What happens is constantly expanding.
Even from a scientific point of view, the brahman has two forms – one is the unmanifest, which is called asambhuti by the sage of the Upanishad. The unmanifest brahman means the zero-brahman, the seed-brahman. Let us imagine the time when it had not started to expand, when the seed had not broken. Then imagine the absolute first moment of expansion – and after that the sprouting, the continual expanding, the growing of the tree. From such a tiny seed, such an enormous tree will grow that thousands of bullock-carts can take rest under its shade. And from that tree will fall innumerable seeds; and from each seed will grow again a vast tree; and again each tree will propagate countless seeds, and from each seed the tree, and seeds and trees and seeds and trees endlessly. Thus a single, minute seed, through its growing process, gives birth to endless seeds. The unmanifest brahman is the seed-brahman, the zero-brahman, the center point. We can only imagine this, because the center point can only be imagined.
If we ask Euclid, the greatest geometrician, he will say a center point is that which has neither breadth nor length. You could not see such a point. This is its definition – it has neither breadth nor length; and it cannot be a point if it has breadth and length, for then it becomes another figure, and there must be expansion. Where breadth and length are, there is expansion. A point is that which has not yet expanded, but which is going to expand. Therefore, says Euclid, the point can only be defined, it cannot be drawn.
When you put the smallest point on a piece of paper with the sharp end of your pencil, there immediately is breadth and length; a point can never be drawn on paper. So the point which is seen has expanded. The point which is not seen, but is defined only, is the true point. The thing which is called the point by Euclid is invisible – it has not yet begun to be; its creation is not yet manifested. It is unmanifest. Life has not yet emerged from it, but it has the potentiality for it; life is yet hidden. So this unmanifest brahman is like the point in the definition.
This is one form of brahman. But we do not know it. We know only the manifest brahman – that which is out. We know the tree-brahman which has unfolded. The manifest is not yet complete, it is becoming and becoming; it is in the process of becoming, it is constantly expanding. Our universe is becoming larger and larger every moment. To describe its increase by the day is too much – it is inconceivable. So I say it expands every second. The stars are moving away from the center at the speed of light. The speed of light is one hundred and eighty-six thousand miles per second. So in one minute it expands sixty times that distance; and in one hour, sixty times that again. And multiply this multiplication by twenty-four to know how many miles it has expanded at the end of one day.
